ROTATING ELECTRICAL MACHINE HAVING IMPROVED BEARING LUBRICATION AND ASSOCIATED METHODS |
摘要 |
A rotating electrical machine includes an outer housing; a drive shaft rotatably mounted within the outer housing; a bearing supporting the drive shaft relative to the outer housing, wherein the outer housing includes a support surface confronting the bearing and the bearing includes a bearing surface confronting the support surface, and further wherein a region defined between the support surface and the bearing surface has a lubrication layer; and a lubrication flow path configured to direct a lubricant to the bearing, wherein the lubrication flow path is in fluid communication with the region between the support surface and the bearing surface so as to replenish the lubrication layer. A method of lubricating a bearing for a rotating electrical machine is also disclosed. The rotating electrical machine may be a generator for a wind turbine. |
